I To all whom, 'it may camera:

Be it known that I, MAX BITrnICH, a subject of the Emperor of Germany, and a resident of Stettin, Germany, have: invented certain new and useful Improvements in Measuring Feed Devices for Retorts and the Like, of' which the following is a vspecification. Y

- My invention relates to feed mechanism for furnaces, retorts and the like, inwhich the amount fed is measured, so that the charge will always be of the same quantity. Devices of this character comprise a storage receptacle and a measuring receptacle adapted to receive its charge from the, storage receptacle, and to thereupon transfer this charge tothe furnace or retort. The manipulation of such devices at the proper timehas hitherto required the close attention of the operator.

My present invention has for its object to so construct the apparatus that automatic means will be provided for insuring the opening and closing of each of the recep tacles at the proper time, that is, the mechanism is so constructed that no material can pass from the storage receptacle to the measuring receptacle unless the outlet of. the measuring receptacle is first closed, and that no material' can pass from the storage receptacle to the measuring receptacle when the latter is opened to discharge its contents.

A practical embodiment of my present invention is shown in the accompanying draw' ings in which- Figure 1 is a side elevation of the apparatus with both receptacles closed; Fig. 2 isa partial side elevation showing the measuring receptacle open; Fig. 3 is a horizontal section on line A-B of Fig. 2; Fig. 4 is an end elevation of the apparatus, and Fig. 5 is a partial vertical section on line C-D of Fig. 2.

In the particular constructionshown, the storage receptacle is represented as a carriage suspended from a truck running on rails. This receptacle has a body 1 and a tapering bottom 2, with which the measuring receptacle 3 is connected by a throat 4. The construction is suchA that when the throat 4 is open, the contents of the storage receptacle will pass quickly to the measuring receptacle. The outlet of the measuring receptacle is normally closed by a swinging gate 5, carried by a shaft 6 which extends through lthemeasuring receptacle. A cuti receptacle and the measuring receptacle, and this device consists of two slides 7, 8, working horizontally in the throat 4. As shownv in Fig. 5, the guides in which the slides 7, 8 move, may be (formed by means of irons 9, 10, an a U-bar 11, with Ydistance pieces 12 interposed between the angle irons and the U-bars. The slides 7, 8 are located at diierent levels and projectV from the apparatus atfopposite sides and are connected by mechanism, to be described presently, in'

such a manner that they will-move 1n opposite directions. Thus the slides 7, 8 may open or close the passage through the throat l 4, and they may even project one above the Y other so as to overlap as .indicated inFig. 2.

In order that the slides may readily pass through the material, their inner edges are sharpened. At their outer ends the slides are' provided with ears 13 and 14 (see Fig. 3), receiving pivot rods 16 and 18 respectively, which carry links 15 and 17 respectively. The outer ends of the links are pivotally connected by means of pins 19, 24 with levers 20, 25 respectively. vers are mounted on shafts 22, 27 respecluatented N0vl2,'1909. l

off device is employed between the storage l angle These 1ei I tively, journaledin brackets Y21, 26 respectively. The levers 20 are connected below their pivots by arod 23 and the levers 25 are connected above their pivots by a rod 29.

.These two rods are linked together by connecting rods 28, extending at each side of the measuring receptacle 3, as indicated -in Figs. 3 and 4. This mechanism insuresa uniform motion of the slides .7, 8 in opposite directions.

On the V'shaft 22 to which levers 2O`l are secured ri 'dly, is arrangedca crank arm 30, connected y a link 31 with a crank arm 32 projected froma rock shaft 34 journalcd in brackets 33. This rock shaft 1s further provided with an operating lever 35 adapted to be worked by hand and having pivotall'y secured to it at 36 a depending bar 38. Thls equilibrium. The proportions of the parts',-

and particularly the location of the pivot 36 and the length of the slot 37 are such that if the operating lever -35 1s moved bar is provided with a longitudinal slot 37 -from the position shown in full lines in which remains. close moved upward to the position indicated b 1 to that indicated by dotted lines this will have no effect on the osition of the gate 5,

dp by its own weight. 42 is a stop to limitthe movement of the swinginggate 5 and 43 is an adjustable wall for varying the volume. of the measuring receptacle. This lWall may for instance be pivoted at itsupper end 43* and -pivotally connected at 43b with an Aadjusting rod 43 which has a series 'of openings 43l any one of which may receive a locking pin 43e also assing through an aperture in a bracket 3f secured to the receptacle 3.

In operation, the parts being in the position illustrated by'solid lines 1n Fig. v1, and the measuring .receptacle being empty, while the storage receptacle contains material to be fed to the retorts or other apparatus, the' material cannot pass from the storage receptacle to the measuring receptacle as the -slides 7 and 8 have their inner edges invertical alinement. nIn order to lill the measuring receptacle, the leverA is then first dotted lines. -Thls, as previousl explain does not affect the posltion oft e swinging gate 5,'since the pin 39 merely slidesin the vupper ends, this causing the slot 37. The connection by means ofthe link 31 and crank arm 30,-rocks the shaft 22 and also the shaft 27, owing to the provision of the connecting rods 28, and thus the levers 20,25 aremoved a art at their des 7 and 8 to clear. thethroat 4, for the passage of the material from the storage receptacle 1 to the measuring receptacle 3, The pin 39 is in en-n 4gagemeni; with the arm 38 at the lowerend of the slot 37, so that the gate 5 cannot move fore the 'accidentally while the Vmaterial Yis passing 1nto.the measuring receptacle. When the device has`-been brought `over Athe retort 44 or other apparatus-liebe charged, the lever 35 1s moved downwardV into, the position ,illustrated by Fig. 2. During the lirs't part A of this movement, from the position shown Jn Vdotted lines in' Fig: 1, to that shown solid lines in the same lfigure, the pin 39 lwill'slde in the slot 37 and thezgate '5 will remain stationary, but the slides 7, 8 will be moved toward each other so as 'to reach. .the position shown in Fig. 1. The connection between the storage receptacle and the measuring receptacle is thus interrupted beate 5 begins to open. Durin the further ownwar movement of the ever 35 the'upper end wall ofjthe slot 37 preses the pin 39downward, and thus swings the gate into the open position illustrated by Fig.l 2. At the same time the inward movement of the slides`7 and 8 is continued causin themto overlap as shown, so that any trick ing of the material from the storage receptacle mto the measuring receptacle is prevented,

Whenthe lever 35 is swung back to the p o-v IIlhe number of the cut-off slides may be.

varied and other modifications may be made Without departing from the nature of my invention as defined in the claims.
